5.1 Formation
Syenites are formed due to alkaline igneous activities and are generally formed in thick continental crustal areas or in Cordilleran subduction zones.
Migmatites form by high temperature regional and thermal metamorphism of protolith rocks where rocks melt partially due to high temperature.

Syenite vs Migmatite Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Syenite and Migmatite Reserves. Syenite is a coarse-grained igneous rock which is composed mainly of alkali feldspar and various ferromagnesian minerals. Migmatite is typically a granitic rock within a metamorphic host rock which is composed of two intermingled but distinguishable components. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Syenite vs Migmatite information and Syenite vs Migmatite characteristics in the upcoming sections.

Syenite vs Migmatite Characteristics

Though some rocks look identical, they have certain characteristics which distinguish them from others. Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Syenite vs Migmatite characteristics assist us to distinguish and recognize rocks. Also you can check about Properties of Syenite and Properties of Migmatite. Learn more about Syenite vs Migmatite in the next section. The interior uses of Syenite include Flooring, Homes, Hotels and Interior decoration whereas the interior uses of Migmatite include Countertops, Flooring and Kitchens. Due to some exceptional properties of Syenite and Migmatite, they have various applications in construction industry. The uses of Syenite in construction industry include As dimension stone, Cement manufacture, Construction aggregate, For road aggregate, Landscaping, Making natural cement, Manufacture of magnesium and dolomite refractories and that of Migmatite include As dimension stone, Cement manufacture, For road aggregate, Making natural cement.

More about Syenite and Migmatite

Here you can know more about Syenite and Migmatite. The life cycle of a rock consists of formation of rock, composition of rock and transformation of rock. The composition of Syenite and Migmatite consists of mineral content and compound content. The mineral content of Syenite includes Amphibole, Biotite, Feldspar, Hornblade, Micas, Muscovite or Illite, Plagioclase, Pyroxene, Quartz and mineral content of Migmatite includes Biotite, Chlorite, Feldspar, Garnet, Graphite, Hornblade, Micas, Muscovite or Illite, Quartz, Quartzite, Silica, Zircon. You can also check out the list of all Igneous Rocks. When we have to compare Syenite vs Migmatite, the texture, color and appearance plays an important role in determining the type of rock. Syenite is available in brown, buff, cream, green, grey, pink, white colors whereas, Migmatite is available in black, bluish - grey, brown, brown- black, dark greenish - grey, dark grey to black colors. Appearance of Syenite is Banded and Foilated and that of Migmatite is Dull, Banded and Foilated. Properties of rock is another aspect for Syenite vs Migmatite. The hardness of Syenite is 5.5-6 and that of Migmatite is 5.5-6.5. The types of Syenite are Shonkinite whereas types of Migmatite are Diatexites and Metatexites. Streak of rock is the color of powder produced when it is dragged across an unweathered surface. The streak of Syenite and Migmatite is white. The specific heat capacity of Syenite is 0.92 kJ/Kg K and that of Migmatite is Not Available. Depending on the properties like hardness, toughness, specific heat capacity, porosity etc., rocks are resistant to heat, wear, impact, etc.Syenite is heat resistant, impact resistant, wear resistant whereas Migmatite is heat resistant, pressure resistant.
